I have done a bit of this parkrun tourist thing. I even met my other half while we were both parkrun touristing. A parkrun tourist is someone who runs, walks or volunteers at a different parkrun location every week instead of just going to their local free timed five kilometre event.
It took peer group pressure to get me hooked on being that keen to adventure to new and wonder parkrun events regularly. I was happy enough just running as fast as I could each week and my nearest one. To be truthful I thought it was a bit weird when a running friend wanted to travel to the other side of town for a run but tagging along with him and then meeting @consciouscat has got me going all over the place whenever we can.
We have slowed down a bit now but with over a 100 different locations done and a tourist streak of 44 different ones in a row it was close to being an obsession. I suppose while working a high stress job it was a great outlet to get away and focus on something completely different than work. There are multiple different apps that automatically track all your destinations, challenges and times.
